Need suggestion regarding WordPress theme

I'm planning to start a blog related to Windows & Mac issues but not able to find any appropriate theme regarding that. Can someone help me out to find the themes used by these websites? Also, if you've got any theme related to solutions in your mind then feel free to mention it.
